Which of these is an example of a chemical change? a fireworks exploding b grinding powder c melting cheese d ironing a shirt

A. Fireworks exploding is the answer

Hey There,

Your answer is A) Fireworks exploding

This is an action of chemical change. Grinding powder, melting cheese and ironing a shirt are all action of physical change. You are just changing their form, not performing a chemical change. When fireworks explode, a chemical inside of them changes.

Best Of Luck,
